The Problems
Metal roofs and cladding are not sealed to the roof deck or sheathing, which allows moisture to easily get underneath the metal.
If moisture is allowed to accumulate under the metal, two problems can arise. The first is that moisture can prematurely damage the roof substructure, requiring removal of the metal and repair. The second problem is that moisture can condense on the underside of the metal, which can lead to corrosion, requiring the metal to be replaced sooner than necessary.
The Solution
DELTA®-TRELA is a vapor permeable underlayment with structured separation and drainage, specifically designed for metal roofs and façades with metal cladding. The underlayment prevents corrosion and moisture accumulation underneath panels, ensuring the longevity of your metal roof. Passive House High-performance building material.
